Answer to Question #286426 in Classical Mechanics for alex

Question

Water is driven through an horizontal pipe at constant pressure (pi). The pipe has a constriction

along its length. At places where the pipe becomes narrower, the pressure p2 at that location

satisfies:

a. p1 = p2

b. p1>p2

C. p1<p2

d. It is possible for p, may be either higher than, lower than or equal to p2 .

Answer 1

The answer is (b) because higher speed means lower pressure.
